TYPE-WRITER.

Specification of Letters Patent.

Patented Nov. 25, 1913.

Application filed August 13, 1913. Serial No. 784,562.

To all whom it may concern Be it known that I, ALois VAN LoY, a subject of the King of the Belgians, and residing at Brussels, in the Kingdom of Belgium, have invented new and useful Improvements in Type-VVriters; and I do here-v by declare the following tobe a full, clear, and exact description of the same.

My present invention relates to typewriters and particularly to typewriters without the usual keyboard.

The primary object of my invention is to provide a typewriter of this class having a typecarrier made of spherical segmental form and in which the printing of the types requires only little strain. In other typewriters of this class, the hand of the operator guides the movements of the pointing key in both directions above the index plate for adjusting the type to be printed, and at the same time the hand causes the adjusted type to be printed by pressing the key downwardly. Among the two strains which the operators hand has to produce, the strain required for pressing the key downwardly is the highest. These strains upon the hand fatigue the wrist and make quick writing impossible. Therefore another object of this invention is to minimize these strains upon the hand.

The objects of my invention are attained by the fact that themuscular force of the operators hand acts through the agency of a pointing key upon the free end of a single-armed lever, capable of swinging in a vertical plane and carrying the type-carrier at a point between its ends, whereby any gear-wheel for actuating thesegmental type-carrier will be omitted, while at the same time the force to be produced by the operators hand will be reduced to a fraction of the strain necessary for printing a type as said force acts upon the free end of a single-armed lever.

In the typewriter according to this invention the pointing key and type-carrier are moved in unison through the agency of a forked rod, forming a jointed parallelogram together with the suspensionarm of the type-carrier, the pointing key and the said' printing lever, said parallelogram being ca-' pable of turning around the longitudinal axis of the printing lever. In this way the lower end of the pointing key may be moved in any direct-ion (forwardly and backwardly by being swung at the end of the printing lever in the plane of the jointed parallelogram, and to the right and left by causing the plane of the parallelogram to swing around the'longitudinal axis of the printing lever) upon the ind-ex plate. Upon each movement the pointing key actuates the type-carrier for adjusting the type to be printed. The lower end of the key being adjusted for printing the desired type, all that is necessary is to press the key downwardly by compressing a weak spring for printing the desired type. The exact adjustment of the type to be printed, the feeding ofthe carriage and the inking device are obtained and actuated by suitable devices which do not form a part of this invention.

My invention will be more clearly understood from the following description taken in connection with the accompanying drawings, wherein Figure 1. shows a side elevation of a typewriter constructed in accordance with my invention, Fig. 2. is a top plan view of same, and Figs. 3 and 4. show diagrammatical side and front views of the improved typewriter.

Referring to the drawingsQ designates the base-plate, provided with a spherically recessed index-plate land having on opposite sides suitably formed supporting arms 3, 3, in which is journaled a horizontal shaft 4. Secured to or made integral with said shaft 4 is a stud 5 rojecting forwardly and on which is rotata 1y held the tubular extension 6 of the printing lever 8 having an enlarged bifurcation 7 intermediate its ends. The pointing key 9 is pivotally connected to the free end of said printing lever by means of a pin 10 or in any other suitable way. The spherical. segmental type-carrier 11 is provided with lateral ears or extensions 12, pivotally connected by means of pins 13 to the enlarged bifurcation 7 of the printing lever 8. Pivotally connected to the body of the type-carrier 11 is the forked end 14: of a rod 15, the opposite also forked end 16 of which is pivotally connected by means of a pin 17 to the key 9.

The printing lever 8 and rod 15 together with the key 9 and type-carrier 11 and the arms 12 of the latter form the sides of a jointed parallelogram, enabling the tip of the key to be brought upon any desired leting position (Fig. 8). As the jointed parallelogram is capable of turning as a whole aroundthe stud 5, it will be seen that the key, 9 may also be adjusted laterally (Fig. t), the type-carrier 11 being at the same time: adjusted correspondingly. The carriage which carries the paper-roller 18 is caused in any suitable way to move in guideways of the base-plate 2.7 i

I wish it to be understood that the various parts of the typewriter described and shownmay be made of any desired form,

Without departing fromvthe scopeof the invention.

Having fully described my invention, what 7 V I claim and desire to secure by Letters Patent is 1. In a typewriter of the class described, the combination with a suitable frame, an indeX-plateand the usual carriage slidably arranged on, said frame, of a horizontal "shaft, journaled on the frame, a single armed printing lever carried by said shaft, a pointing key, pivotally connected to the free end of said lever,a spherical segmen- Qtal type-carrier suspended from the print ing lever intermediate the ends of the lat ter, means for causing the pointing key and type-carrier to be moved in unison, and means enabling the printing lever to turn 1 around its longitudinal axis, substantially as set forth. 7

, 2. In a typewriter of the class described, the combination with a suitable frame, an index-plate on the same and the usual carriage slidably arranged on said frame, of a horizontal shaft journaled on said frame, a

a suitable type-carrier, pivotally connected to the printing lever intermediate the ends of the latter, and means for causing the a pointing key and type-carrier to be moved in unison, substantially as set forth.

3. In a typewriter of the class described, the combination with a suitable frame, an index-plate on the same and the usual carriage slidably arranged on said frame, of a horizontal shaft journaled on said frame, a forwardly projecting stud on said shaft, a single-armed printing lever one end of which is rotatably held on said stud, a pointing key pivotally connected to the free end of the printing lever above said index-plate, a suitable type-carrier pivotally connected to the printing lever intermediate the ends of the latter, and a suitable rod pivotally c0nnected at opposite ends to the body of the type-carrier and the pointing key respectively, whereby the printing lever, type'carrier, pointing key and said rod form a jointed parallelogram, capable of turning around the longitudinal axis of the printing lever and swinging in a vertical plane around the said horizontal shaft, substantially as set forth.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

ALOIS VAN LOY.
